Waves
Across
- 2. cycles per second
- 3. strength of wave
- 6. compared structures with equal echogenicity
- 9. velocity of wave movement
- 10. length of one cycle
- 13. effect of changed freq from reflector motion
- 14. object with internal echos
- 15. sound waves detected by transducer
Down
- 1. events per unit of time
- 4. type of wave that requires a medium
- 5. particles moving same direction to wave
- 7. anechoic with well defined walls
- 8. particles moving perpendicular to wave
- 11. no amplitude
- 12. sound waves generated by transducer
